ABSTRACT

Device holders having a number of arms for receiving a handheld device and a number of recesses providing an interface area for a user&#39;s hand to hold the device during use. In some examples the device holder maintains an open cavity between the body of the device and the holder itself. In some examples, the holder maintains the device in place with a series of extensions from the base of the holder that secure the periphery of the device via a retainer.

BACKGROUND

The present disclosure relates generally to handheld device holders. In particular this disclosure includes handheld device holders having strategically placed gripping recesses and device protection cavities.

There exist a large variety of handheld devices on the market today. These devices come in all shapes and sizes and vary in function and purpose. These devices range from standard cellular phones, to smart phones, to gaming devices, global positioning units, tablet computers, laptops and more. These devices serve a myriad of purposes and are carried everywhere a user goes. Because these devices are handheld, users often seek comfortable and efficient ways to secure these devices during use and protect them from damage.

Known device holders are not entirely satisfactory for the range of applications in which they are employed. For example, existing device holders lack gripping recesses conducive to increasing a user's hold on a device. Existing device holders allow a very limited number of holding positions for a user. These positions often place the device in precarious and difficult to maintain positions in a user's hands.

Existing holders often cause user discomfort in that they force a user to endure often uncomfortable and non-ergonomic hand positions when interfacing with a device. Such positions can lead to Fatigue and increase the likelihood that a device will fall or be dropped by the user causing damage to the device.

Extant device holders are also attached too close to the body of the device to allow for proper gripping recesses. A user maintains significantly more control over a device when the hand and fingers can penetrate the holder's recesses. Existing device holders do not allow adequate space between the body of the device and the holder itself for users to grip the holder.

Additionally, known device holders provide inadequate protection to the device. Damage to the device results when the device is dropped and contacts a hard surface, Existing holders are wrapped to closely around the body of the device and fail to provide sufficient impact resistance for the device. A holder having inadequate cavity between the device body and the holder allows the full force of impact to be transferred to a device.

Ease of use, comfort in handling, and protection from damage are of utmost importance for device users, Current holders have failed to sufficiently incorporate these needs into a single functional design. Thus, there exists a need for device holders that improve upon and advance the design of known device holders. Examples of new and useful device holders relevant to the needs existing in the field are discussed below.

SUMMARY

The present disclosure is directed to device holders having a number of arms for receiving a handheld device and a number of recesses providing an interface area for a user's hand to hold the device during use. In some examples the device holder maintains an open cavity between the body of the device and the holder itself. In some examples, the holder maintains the device in place with a series of extensions from the base of the holder that secure the periphery of the device via a retainer.

DETAILED DESCRIPTION

The disclosed device holders will become better understood through review of the following detailed description in conjunction with the figures. The detailed description and figures provide merely examples of the various inventions described herein. Those skilled in the art will understand that the disclosed examples may be varied, modified, and altered without departing from the scope of the inventions described herein, Many variations are contemplated for different applications and design considerations; however, for the sake of brevity, each and every contemplated variation is not individually described in the following detailed description.

Throughout the following detailed description, examples of various device holders are provided. Related features in the examples may be identical, similar, or dissimilar in different examples. For the sake of brevity, related features will not be redundantly explained in each example. Instead, the use of related feature names will cue the reader that the feature with a related feature name may be similar to the related feature in an example explained previously. Features specific to a given example will be described in that particular example. The reader should understand that a given feature need not be the same or similar to the specific portrayal of a related feature in any given figure or example.

With reference to FIGS. 1-7, a first example of a device holder, device holder 100 will now be described. Device holder 100 includes a base 102, a plurality of finger holes 104, a first arm 110, a second arm 112, each arm having a terminal end 114 and a retainer 116, a cavity 120 defined by the interior of the base 102. Device holder 100 functions to provide secure holding positions for the user of a device. Additionally or alternatively, device holder 100 can provide impact resistance and protection from damage.

By way of example, reference is also made to a device 150 and a user interacting with device holder 100. These examples do not limit the device holder in any way and only represent a sample of the devices with which the instant embodiment may be used.

As can be seen in FIGS. 1-7, base 102 defines a central portion of device holder 100. Base 102 represents any portion of device holder 100 that the user would interface with for holding device holder 100. In the instant example, base 102 is mostly planar having outer and inner surfaces. The edges of base 102 taper towards the device to create an overall rounded shape. In another example, the base takes on a rectangular shape. In yet other examples, the base is selected from a number of different shapes suitable for cradling a device and allowing a user to increase the stability with which the device is held.

In this example base 102 is composed of a flexible plastic. A significant number of materials and composites are employed in various other examples. In another example the base is made of aluminum. In yet another example the base is made of rubber. In other examples any material that can reasonably create a holding surface for user interface is contemplated.

Base 102 provides a surface into which finger holes 104 extend. Base 102 constitutes a structure within which space is provided for gripping device holder 100, Material can be removed from any portion of base 102 creating finger holes 104.

Turning our attention more specifically to FIG. 1, we see finger holes 104 extending into base 102 of device holder 100. In this example, a number of finger holes 104 are present on base 102. In another example, there is only a single hole to provide a gripping surface. In yet other examples, there are many holes covering the base of the device holder.

In the present embodiment, finger holes 104 are arranged in a circular pattern. In various examples, finger holes may be arranged in patterns conducive to user interface. In yet other examples, finger hole placement is specifically optimized for user interface and/or mounted attachment interface.

Referencing FIG. 1, a user is shown interfacing with device holder 100 by inserting his fingers into finger holes 104. The user is depicted having inserted his thumb into one finger hole 104 towards the bottom of base 102 in device holder 100, and also having inserted his pointer and middle fingers into finger holes 104 opposite the thumb. This figure shows only one possible way for a user to engage device holder 100.

The ranges of devices that may be used with device holder 100 serve numerous functions. As such, user preferred holding positions differ between the varying functions and device orientations. In FIG. 1, device 150 is being used in a horizontal position. In an alternate example, where the device being used is in its vertical position, the user would need only to rotate the device holder to gain access to alternative finger holes, maintaining largely the same hand position despite a change in device orientation.

By way of explanation only, a device holder may be used in conjunction with a handheld gaming device. A user needing to turn the device or move it rapidly in his hands would elect a particular hand position to accomplish such mobility. On the other hand a device holder being used with a handheld electronic sketch pad would cause a user to elect a different hand position offering more stationary stability.

We also see in FIG. 2 that finger holes 104 vary in size relative to one another. Just as finger hole placement on the device holder can be varied to achieve optimal interfacing for a given use, finger hole size may also be varied. Though FIG. 2 shows finger holes 104 having alternating sizes relative to one another, in another example the holes are the same size relative to one another. In various examples, the device holder has finger holes which range from small (approx. 0.5 inches in diameter) to large (greater than 2 inches in diameter).

Further, FIGS. 1-4 show finger holes 104 which are largely circular in appearance, while in some examples circular finger hole shape may be optimal for a given use, other examples include finger holes having non-circular shape. In a certain example, the finger holes are oval. In another example, the finger holes are square.

Turning now to FIG. 2, a central finger hole 104(i) is shown. In the instant example central finger hole 104(i) is a standard finger hole having characteristics similar to other finger holes 104. As described above, device holder 100 will be interfaced by users and mounted attachments alike. In the instant embodiment finger hole 104(i) represents an interface location for mounted attachments. FIG. 5 further shows finger hole 104(i) in a standard user interface configuration. In contrast, FIG. 7 depicts finger hole 104(i) being interfaced by a mounted attachment 140.

Any number of mounted attachments may be attached to any of finger holes 104. In the instant example the mounted attachment is an adjustable clamping arm 140. Clamping arm 140 has been optionally interfaced with central finger hole 104(i). In various other embodiments the mounted attachment is a wall mount, a table top stand, or an automotive dash attachment. In each of the various embodiments, mounted attachments are able to interface using any of the unused finger holes.

Directing attention now to FIGS. 5-6, arms 110 and 112 will now be described. Arms 110 and 112 originate on base 102 and extend transverse to a plane defined by base 102. Arm 110 terminates in a first terminal end 114 and a retainer 116 on the periphery of device 150. Arm 112 also has a terminal end and retainer substantially identical to those of arm 110 and will not be redundantly described. Also, by way of example only, the current embodiment includes right arm 112(i) and left arm 112(ii) both arms having features substantially identical to arms 110 and 112. Some alternative embodiments include only two arms while yet other embodiments include more than two arms.

In the instant embodiment, arms 110 and 112 extend seamlessly in one piece from base 102 towards the periphery of device 150 in opposing directions. Arm 110 for example, extends from the top of base 102 towards the top of device 150 whereon the terminal end 114 of arm 110 contacts the peripheral edge of device 150.

In contrast, arm 112 extends from the bottom of base 102 towards the bottom of device 150 terminating on the bottom peripheral edge of device 150. In a similar configuration, right arm 112(i) and left arm 112(i) extend from base 102 in opposing directions terminating on the right and left peripheral edge respectively, of device 150.

Each of arms 110, 112, 112(i), and 112(ii) are capped at their respective terminal ends with a retainer 116. As can be seen in FIG. 6 for example, the terminal ends of arm 110 and 112 further extend beyond the peripheral edge of device 150 and create retainer 116. In the instant example, retainer 116 folds over the peripheral edge of device 150 onto the face of device 150. In another example, the retainer does not extend onto the face of the device and instead clips solely to the peripheral edge of device 150.

Turning to FIG. 4, retainers 116 are shown cradling the face of device 150. The opposing directions of arms 110, 112, 112(i), and 112(ii) and the terminal ends having retainers 116 create a shape whereby device holder 100 maintains device 150 in a secure position.

Retainers 116 have an outer and inner surface. FIG. 4 shows the outer surface of retainers 116. In the instant example, retainers 116 have an inner surface substantially matching the contour of the outer surface. In another example, the interior surface may curve to match the contour of the device in question. In other examples, the interior surface comprises a lip designed to fit snugly over the peripheral edge of the device contained within the device holder. In yet other examples, the interior surface is made from a flexible material able to conform to the edges of multiple devices.

Turning back to FIG. 6, the peripheral edge of device 150 is shown contacting terminal ends 114 of each arm at such an angle that restricts movement of device 150 laterally or medially within base 102.

As can be seen in FIGS. 5-6, the arms extend from base 102 in a curve precisely toward the peripheral edges of device 150. In this example, the curved shape of arms 110, 112, 112(i), and 112(ii) in conjunction with the semi-rigid nature of device holder 100 causes inward pressure to be exerted on the peripheral edges of device 150. This inward pressure secures the edges of device 150 from movement and allows device holder 100 to provide multiple secure holding positions for the user.

In another example, the arms approach the peripheral edges of the device at a substantially right angle creating a similar inward pressure for holding the device in place. In another example, the device is instead held in place with adhesive. In yet other examples, the device is held in place mechanically and no inward pressure is exerted on the device by the arms.

While in the current example base 102, arms 110,112,112(i), and 112(ii), and the respective terminal ends 114, and retainers 116 are formed from a single piece having no seams, alternative embodiments include bases, arms, terminal ends, and retainers formed from multiple discrete pieces that are joined together to create a single device holder.

In the current example and in various other embodiments, the device holder is configured to receive a lid portion 160. FIG. 6 shows one example of a lid configuration that engages the peripheral edge of device 150 in the spaces between adjacent arms 110, 112, 112(i), and 112(ii). In this example the lid is made from a material substantially similar to that of the base 102 of device holder 100. In yet other embodiments the lid is made from other materials sufficient to provide a covert to the face of the device.

Focusing again on FIG. 6, cavity 120 is now described. The inner surface of base 102 defines a cavity 120, between device holder 100 and device 150. The outer surface of base 102 comes in contact with the user and other interfacing surfaces. Cavity 120 provides a buffer between device 150 and interfacing surfaces and users. Additionally, cavity 120 creates an interstitial space where users may place their fingers for desired holding positions and where mounted attachments engage finger holes 104.

In the instant embodiment, cavity 120 has a contour largely matching the contour of the exterior surface of base 102. The outside edges of cavity 120 are tapered to meet the peripheral edges of device 150. In another example, the cavity does not match the exterior contour of the base but instead is has a unique shape which can be selected for particular characteristics. The cavity in such examples is selected based upon desired mountable attachments, storage, rigidity, flexibility, cushion, weight, etc. In each case the cavity shape is selectable based upon desired interface characteristics.

Turning attention to FIGS. 8-9, a second example of a device holder, device holder 200 will now be described. Device holder 200 includes many similar or identical features to device holder 100. Thus, for the sake of brevity, each feature of device holder 200 will not be redundantly explained. Rather, key distinctions between device holder 200 and device holder 100 will be described in detail and the reader should reference the discussion above for features substantially similar between the two device holders.

As can be seen in FIGS. 8-9, device holder 200 includes a base 202, a plurality of finger holes 204, a first arm 210, a second arm 212, each arm having a terminal end 214 and a retainer 216, a cavity 220 defined by the interior of the base 202. Device holder 200 functions to provide secure holding positions for the user of a device, and secure holding positions for mounted attachments. Additionally or alternatively, device holder 100 can provide impact resistance and protection from damage.

Arms 210, and 212, the relevant terminal ends 214 and retainers 216 are substantially similar to their device 100 counterparts. Additionally, cavity 220 defines a cavity having substantially similar characteristics compared to cavity 120 described above. Finger holes 204 however include an additional feature not present in the embodiment described above. Device holder 200 therefore, additionally includes a mounted attachment friction interface 230 and a support stand 240 for propping the device.

Directing attention now to FIG. 8, friction interface 230 is described. As can be seen in FIG. 8, device holder 200 includes a base 202, into which a plurality of finger holes 204 extend. In the instant example, finger holes 204 vary in size relative to one another. Also in the instant example, finger holes 204 are shown in a circular arrangement toward the center of base 202. In another example, the size and location of the finger holes are random, taking up space across the entirety of base 202. In various other examples finger hole placement on the device holder is varied to achieve optimal interfacing for a given use. Additional embodiments include finger hole sizes that are uniform.

Though FIG. 8 shows finger holes 204 alternating in size relative to one another, in another example the holes remain uniform in size relative to one another. In various examples, the device holder has finger holes which range from small (approx. 0.5 inches in diameter) to large (greater than 2 inches in diameter).

Further, FIGS. 8-9 show finger holes 204 which are largely round in appearance, while in some examples round finger hole shape may be optimal for a given use, other examples include finger holes having non-round shapes. In a certain example the finger holes are oval. In another example the finger holes are square.

Turning now to FIG. 8, a central finger hole 204(i) is shown. In the instant example central finger hole 204(i) is a standard finger hole having characteristics similar to other finger holes 204. As described above, device holder 100 will be interfaced by users and mounted attachments alike. In the instant embodiment finger hole 204(i) represents an interface location for mounted attachments. FIG. 8 shows finger hole 204(i) in a standard user interface configuration. In contrast, FIG. 9 depicts finger hole 204(i) being interfaced by a mounted attachment.

A noticeable addition to finger hole 204(i) when compared to device holder 100, is a friction interface 230. In the instant example, friction interface 230 is arranged in a circular pattern surrounding finger hole 204(i). Friction interface 230 defines a region of base 202 having a series of ribs arranged in a pattern surrounding a finger hole 204. Friction interface 230 provides for controlled adjustment of interfacing mounted attachments.

In the instant embodiment, friction interface 230 defines a series of ribs protruding from the surface of base 202. In another example, the friction interface is comprised of tooth like structures. In yet another embodiment, the friction interface is a series of dimples. In each embodiment including a friction interface, any surface having a sufficient friction coefficient for selectable adjustment of interfacing mounted attachments is contemplated.

Any number of mounted attachments may be attached to any of finger holes 204 and therefore friction interface 230 may likewise be present around any of finger holes 204. In the instant example the mounted attachment is a support stand 240. Support stand 240 has been optionally interfaced with central finger hole 204(i). In various embodiments, support stand 240 is able to interface using any of the unused finger holes 204.

Turning attention now to FIG. 9, support stand 240 is now described. As can be seen in FIG. 9, support stand 240 includes an attachment surface 242, a coupler 244, swivel member 246, and a propping member 248.

In this example, attachment surface 242 engages friction interface 230. Attachment surface 242 is a substantially planar surface configured to create a contact point between device holder 200 and support stand 240. In the instant example, the contacting face of attachment surface 242 is covered with a series of ribs complimentary to the ribs of friction interface 230.

In another embodiment, the attachment surface is covered with tooth-like protrusions configured to compliment the teeth of alternative friction interfaces. In yet another embodiment the attachment surface is dimpled to receive a complimentarily dimpled friction interface, in yet other embodiments, any surface complimentary to an opposing friction interface that allows for controlled adjustment of the support stand is contemplated.

The attachment surface 242 of device holder 200 is coupled to base 202 via a coupler 244. In the instant example, coupler 244 attaches to base 202 through the center of attachment surface 242, through finger hole 204(i) and is fastened into place within cavity 220.

Coupler 244 applies a clamping force on attachment surface 242 pulling it into contact with friction interface 230. In this example, coupler 244 is a standard bolt retained in place with a nut as known in the art. The bolt extends through the attachment surface and through the finger hole and is retained from within the cavity causing a clamping force to be exerted on all surfaces and hold the support stand to the device holder. The amount of clamping force exerted by coupler 244 on the attachment surface 242 is adjustable by tightening the nut.

In this example, a clamping force that allows for selectable adjustment of the angle of attachment of the stand, but sufficient to withstand sagging or unwanted movement is preferable. In another example, the coupler is a pin that is retained in place with a spring, the spring being disposed on the interior surface of the cavity. In such example, the amount of clamping force exerted by the coupler on the attachment surface is a function of the tension exerted by the spring.

When sufficient clamping force is exerted, drawing base 202 together with attachment surface 242 via coupler 244, support stand 240 can be rotated in intervals around the friction interface between corresponding ribs. Device holder 200 supplies support, protection and holding positions for a large number of devices, each of which often have multiple positions of use. Support stand 240 allows articulation of device holder 200 across a range of positions and orientations.

Support stand 240 is rotatably adjustable around the axis of coupler 244. As support stand 240 rotates around the axis, attachment surface 242 intermittently engages the ribs of friction interface 230 making support stand 240 selectably adjustable in three-hundred-and-sixty degrees.

Turning back to FIG. 9, coupler 244 additionally provides a point of attachment for a swivel member 246. Swivel member 246 provides for articulation of device holder 200 relative to support stand 240. In the instant example, swivel member 246 defines a pin structure that connects a propping member 248 to coupler 244 providing for a swivel movement between the two structures. The pin structure of swivel member 246 transects both propping member 248 and attachment surface 242.

Swivel member 246 allows propping member 248 to open away from base 202 sufficient to provide standing support for device 200. In this embodiment, swivel member 246 is free floating and acts as a common bushing between the propping member and attachment surface. In another embodiment the swivel member is configured to selectively apply a clamping force between the propping member and the attachment surface. Such a clamping force allows for selective positioning angle of the propping member.

Turning attention now to propping member 248. FIG. 9 depicts a propping member 248 secured to the attachment surface via swivel member 246. In the instant example, propping member 248 comprises a leg portion of support stand 240. Propping member 248 is configured to rest on any structure like a table or other surface that a user would commonly place a device on during use. Propping member 248 provides a contact point with a surface which in addition to the contact points created by the periphery of device 150, cause device 150 to remain upright during use.

FIG. 9 depicts a common standing position created by propping member 248. In the instant example, propping member 248 is a plastic material having a contour matching the outside contour of base 202. In another example, the propping member is made of metal. In various other embodiments, the propping member is composed of any material sufficiently rigid to allow the device to stand upright without additional support.

The contour of propping member 248 allows for a compact stowing position. FIG. 9 shows that in the instant example, propping member 248 has a contour that is complimentary to the shape of base 202. This contour creates a stowing position where propping member 248 is nested around the outer edge of base 202. In another embodiment, the propping member is not contoured but instead is substantially planar. In another example, the contour of the propping member includes one or more right angles and does not nest against the base.
